EDWARD S. BOYNTON, OF BRIDGEPORT, CONNECTICUT.

STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 279,478, dated June 12, 1883.

Application filed March 2, 1883. (No model.)

To all whom it may concern q V Be it known that I, EDWARD STANLEY BOYNTON, of Bridgeport, county of Fairfield,

State of Connecticut, have invented a new and useful Improvement in Station Indicators, which is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a frontview of my improved in ..dicator; Fig. 2, a cut section of the cylinder and a portion of the bracket supporting it; Fig. 3, an end view of the indicator; Fig. 4, a section of the cylinder and cards and cardsupporting mechanism; Fig. 5, a front View of one of the cards.

ment from'any of the numerous causes which affect the action of mechanisms of that kind as heretofore used.

It consists of a cylinder, A, with an aper-, ture, B, therein, provided with card-stops C and C, supported in bracket D by shaft E and pivot G; a card-supporting mechanism composed of two sets of radial arms, H H, securely affixed to the shaft E, of sufficient length to form pockets for the cards, and of any requisite number; a toothed wheel, J, affixed-to shaft E, having teeth on its circumference corresponding in number to the radial arms employed; a second tooth-wheel, K, affixed to one end of cylinder A, having one tooth more than wheel J toothed wheel L, preferably having the same number of teeth as wheel K, supported by shaft M in bracket D, and cards N, with the desired information on the faces thereof.

The action of these several parts will be readily understood. The pinion L being revolved once, the toothed wheel K, affixed to cylinder A, is revolved a complete revolution and the toothed wheel J is revolved a complete revolution and the space of a pocket in addition, the teeth of wheel J being one less in number than the teeth of wheel K. Each exposed card N, in turn, as it approaches the top of the cylinder, will drop within the pocket of its corresponding radial arm, and as it approaches the bottom of the cylinder will fall into card-stops C C, exhibiting the matter on the face thereof to the observer.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A station-indicator consisting, substantially as before set forth, of a revoluble cylinder provided with a longitudinal slot, a frame provided with card-pockets and adapted to revolve within'said cylinder, card-stops secured to the cylinder opposite its slot, and means for revolving the cylinder and card-frame at different speeds.

2. The combination, substantially as before set forth, of the card-frame fixed upon a shaft, the cylinder mountedto revolve upon said shaft, a pinion, K, secured to the head of the cylinder, a pinion, J, having a less number of teeth, secured to the shaft beside the pinion K, and a pinion, L, secured to a separate shaft and meshing with both the pinions J and K.
